johnnny83 on "Update to 1.4.4.3 - another Error 500"

Hello together,

so I read every 500 error post I could find, tried everything mentioned but after a couple of hours I have no ideas anymore...

After updating from 1.4.0.3. to 1.4.4.3 I get an empty page when calling the index.php. Just with using Firebug I could find out that it's an 500 error. On the other hand I can normally access the admin panel.

What I tried:
- deleting .htaccess
- deleting IndexIgnore line
- turning RewriteEngine on and off
- turning Mod_rewrite on and off
- restarting setup

PHP version 5.3.21
MySQLi version 5.1.66

I would be glad for any suggestions!
